Each Family May Have Schizophrenia In Its Own Way : Shots - Health News : NPR
I'm wondering for those who have family who is also sick if the symptoms are the same. My grandma used to hear voices when she went to the grocery store. Unfortunately she passed a long time ago so I cannot ask for more details but I think she was high functioning becuase she never even saw a psychiatrist and most of the family never knew she was sick.
